You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO).
You create the following objects in the solution:
a DataSet object named AWDataSet that contains two tables named Product and SalesOrderDetail
a BindingSource object named ProductsBindingSource
a bookmark that is bound to the SalesOrderDetail table You need to retrieve the active row from the solution .
Which code segment should you use?

• A. AWDataSet.ProductRow pr = ( AWDataSet.ProductRow )((( DataRowView )( this.productBindingSource.DataSource )).Row);
• B. AWDataSet.ProductRow pr = ( AWDataSet.ProductRow )((( DataRowView )( this.productBindingSource.Current )).Row);
• C. AWDataSet.ProductRow pr = ( AWDataSet.ProductRow )((( DataRowView )( this.productBindingSource.SyncRoot )).Row);
• D. AWDataSet.ProductRow pr = ( AWDataSet.ProductRow )((( DataRowView )( (object)this.productBindingSource.Filter)).Row);

You are creating a document-level solution for Microsoft Office Word 2003 by using Visual Studio Tools for the Microsoft Office System (VSTO). The document is customized to add a toolbar with custom functionality. You write the following lines of code in the Startup event of the ThisDocument class.
Dim toolbar As Office.CommandBar = Me.Application . _ CommandBars.Add (Name:=" MyToolBar ", _ Position:= Office.MsoBarPosition.msoBarTop , Temporary:=False)
Dim button As Office.CommandBarButton = _ CType ( too lbar.Controls.Add ( _ Type:= Office.MsoControlType.msoControlButton , _ Temporary:=False), Office.CommandBarButton )
Dim btnClick As _ Office._CommandBarButtonEvents_ClickEventHandler = _ AddressOf Me.button_Click
AddHandler button.Click , AddressOf Me.b utton_Click The event handler for the button does not execute every time CommandBarButton is clicked.
You need to ensure that the event handler executes every time CommandBarButton is clicked.
What should you do?

• A. Change the scope of the CommandBarButton button variable to a class-scoped variable.
• B. Set the Enabled property of the CommandBarButton button object to True.
• C. Set the OnAction property of the CommandBarButton button object to Click.
• D. Change the scope of the ._CommandBarButtonEvents_ClickEventHandler delegate btnClick variable to a class-scoped variable.

You create an add-in for Microsoft Office Visio by using Visual Studio Tools for the Microsoft Office System (VSTO). You install the add-in in a secure environment where local assemblies are not granted the FullTrust permission. You need to ensure that the add-in acquires the FullTrust permission after installation. What should you do?

• A. Configure the File System Editor to copy the add-in assembly to the global assembly cache.
• B. Configure the Custom Actions Editor to copy the add-in assembly to the %WINDIR% folder.
• C. Create an Installer class in the add-in assembly. Override the Install method so that the class associates the assembly with the LocalIntranet code group.
• D. Create an Installer class in the add-in assembly. Override the Install method so that the class copies the add-in assembly to the %WINDIR%/SYSTEM32 folder.

You create an add-in for Microsoft Office Excel by using Visual Studio Tools for the Microsoft Office System (VSTO). You create the following method in the add-in.
Private Sub DisplayTotal(ByVal rng As Excel.Range) 'Display total End Sub
You write the following code segment in the startup event of the add-in.
Dim ws As Excel.Worksheet = CType _ (Globals.ThisAddIn.Application.ActiveSheet, Excel.Worksheet)
AddHandler ws.SelectionChange, AddressOf Me.ws_SelectionChange
The add-in must display the sum of the values in a selected range. If multiple ranges are selected, the add-in must display only the sum of the values in the first selected range.
You need to meet the outlined requirements.
Which code segment should you use?

• A. Private Overloads Sub ws_SelectionChange _ (ByVal Target As Excel.Range) DisplayTotal(Target.Previous) End Sub
• B. Private Overloads Sub ws_SelectionChange _ (ByVal Target As Excel.Range) DisplayTotal(Target.CurrentRegion) End Sub
• C. Private Overloads Sub ws_SelectionChange _ (ByVal Target As Excel.Range) DisplayTotal(Target.Areas(1)) End Sub
• D. Private Overloads Sub ws_SelectionChange _ (ByVal Target As Excel.Range) DisplayTotal(Target.Areas(0)) End Sub
